CHARLES M. CLARKE, OF PITTSBURG, PENNSYLVANIA;

MACHINE FOR ORNAMENTING WOOD OR OTHER SURFACES.

SPECIFICATION forming part of Letters Patent No. 467,155, dated January19, 1892.

Application filed July 1, 1891. Serial No. 398,103. (No model.)

.To all 1022,0722, it may concern:

Be it known that I, CHARLES M. CLARKE, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for 'Ornamenting \Vood, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure 1 is a side elevation of my improved machine. Fig. 2 is avertical longitudinal central section thereof on the line II II of Fig.3. Fig. 3 is a vertical cross-section on the line III III of Fig. 2.Fig. 4. is asectional plan View of the machine, the section being on theline IV IV of Fig. 3. Fig. 5 is a plan view of part of the stencilemployed in the machine. Fig. 6 is a vertical cross-section on the lineVI VI of Fig. 5. Figs. 7, 8, and 9 are plan views of stencils providedwith various patterns.

Like symbols of reference indicate like parts in each.

The purpose of my invention is to provide efficient and rapid means forornamenting wood by forming on the surface thereof an indented patternof the desired configuration adapted to be filled afterward with afiller paste or enamel; and it consists in a machine of improvedconstruction which I have devised for performing this work, whichmachine is herein described fully, and the novel features of which are-specifically indicated in the claims.

In the drawings, 2 represents the table of the machine, which may bemounted on a suitable frame 3, and is adapted to support the board orstrip of wood 4. intended to be ornamented. The wood is fed through themachine in the direction of the arrow b by means of driven feed-rollers5, whose periphcries bear against the wood and by revolution feed itforward.

the tension of the stencil-baud. Along each margin of the band is a rowof indentations or projections 9, adapted to be engaged by a toothedroller 11, driven by gearing 13, so as to rotate at the same surfacespeed with the feed-rollers 5, with which said gearing connects them.The driven roller 12 is a feed and guide roller bearing on the stencil.The rotation of these rollers causes the stencilbaud to travel aroundthe series of guiderollers 7 at the same rate at which the board 4 ismoved by the feed-rollers, and as the rollers 11 12 (or other rollers ofthe series) are set in proximity to the surface of the board thestencil-band is caused to pass for a considerable portion of its travelin contact with the latter. lhe band is perforated with holes after themanner of a stencil, and the holes are of such shape, size, and relativeposi'tion as to be adapted to reproduce on the wood the desired pattern.lVhere it is desired that the woodshould be ornamented with a surfacepattern in imitation of the grain of hard wood, such as oak, the holesare arranged to conform to the surface pores of the variety of wood tobe imitated. This is shown in Figs. 4, 5, and 6. The stencil, however,may be ornamented with any other pattern, as illustrated in Figs. 7, 8,and 9.

For the purpose of applying a blast of sand or other abrasive material Iemploy a blastpipe 14, whose discharge end is directly above the placeof contact of the stencil-belt with the board and which is divided orcurved as shown in Fig. 3, in order to clear the outer branch of thestencil-belt. The upper end of the blast-pipe is connected with areservoir 15, containing sand or other abrasive material-for example,granules of cast-iron or steel-and a pipe or series of pipes 16 entersthe blast-pipe and discharges thereinto com pressed air or steam for thepurpose of oreating a blast which will carry the abrasive material fromhe reservoir and will discharge it with suit i ent violence against thestencil.

In order to remove the sand from the stencil after it has performed itswork, I employ an eduction-pipe 17 which may extend adjacently to thepipe 14., and the open lower end of which is in proximity to thedischarge end of the latter. The pipe 17 is connected with a fan orother suction device 18, driven by suitable mechanism, such as beltingl9, and which serves to draw up the abrasive material from the stenciland to deliver it into a receiver 20.

The operation is as follows: The board 4., having been introduced intothe machine, is carried therethrough by the action of the feed-rollers,and the stencil-band travels in contact with the board and at the samerate of speed. The compressed air or steam is delivered from the pipe 16into the blast-pipe and causes the abrasive material to be forced in astrong jet against the stencil, where, act ing through the holes in thestencil, it engages the wood and cuts the surface thereof, so as toproduce indentations corresponding to the pattern of the stencil. Havingthus performed its work, the abrasive material is drawn off by the pipe17 and is delivered to the receiver 20, together with the particles ofwood which have been worn off by its abrasion. This action of themachine continues until the entire length of the board has been fedthrough it, and as the stencil is in the form of an endless band itproduces a continuous pattern, while itsaction, being uninterrupted, israpid and regular.

The apparatus may be used not only for ornamenting wood, but fortreating metals, pa-

er-board, or other material.

The form and details of construction of the machine maybe varied in widelimits by those skilled in the art, since, although I intend to claimspecifically the illustrated form, the broader claims of the applicationare not limited thereto, and within the scope of the method claimed anyform of stencil, Whether continuous or otherwise, used in any kind ofmachine may be employed.

The advantages of the machine will be appreciated by those skilled inthe art. It affords facility for producing intricate designs, and is notlimited, as are most other indentin g-machines, to producing straightpatterns in the lines of the grain.

I claim 1. In a machine for ornamenting Wood or other surfaces, anendless stencil, means for moving the stencil and the material to beornamented at an equal rate, and a blast-pipe adapted to force abrasivematerial against the stencil, substantially as and for the purposesdescribed.

2. In a machine for ornamenting wood or other surfaces, the combinationof feed-rollers, an endless stencil, driving-gear by which the stencilis caused to move at the same speed as the material to be ornamented,and a blast pipe adapted to force abrasive material against the stencil,substantially as and for the purposes described. v

3. In a machine for ornamenting Wood or other surfaces, an endlessstencil, guides around which the stencil passes, and a blastpipe dividedto permit passage of the stencil, substantially as and for the purposesdescribed.

4. In a machine for ornamenting wood or other surfaces, the combinationof a stencil, a blast-pipe for supplying abrasive material thereto, andan eduction-pipe and fan for removing the abrasive material andcuttings, substantially as and for the purposes described. V

5. In a machine for ornamenting Wood or other surfaces, an endlessstencil, guides by which it is held in contact with the board for aconsiderable portion of its length, and means for supplying abrasivematerial, substantially as and for the purposes described.

6. In a machine for ornamenting wood or other surfaces, an endlessstencil having projections or indentations thereon, and a feedrollerengaging said projections or indentations, substantially as and for thepurposes described.

In testimony whereof I have hereunto set my hand this 20th day of June,A. I). 1891.

CHARLES M. CLARKE.
